Avseal® blind sealing plugs are unique in the efficient sealing performance provided in both low- and high-pressure hole-sealing applications.

This rapidly installed two-piece sealing plug improves quality and safety in demanding applications while simplifying hole preparation and installation, reducing assembly costs. Typical applications include engine blocks, transmissions, cylinders, brakes, gear box, pneumatic systems, hydraulic blocks, compressors, and pumps.

Avseal® sealing plugs can be installed rapidly into blind holes and eliminate the need for tapping threads in the application. Pulling of the steel stem with a conventional Avdel® riveting tool expands the aluminium sleeve to securely seal blind holes having a normal drilled surface.

Avseal® plugs seal fluids including water, coolant, and oils at high pressures.

The Avseal® process is quicker, more reliable, requires no setting of torque, and provides significant cost saving versus conventional threaded plugs.

Many finish options are offered to ensure excellent corrosion resistance.

Fast Facts:

  • Blind hole, one-sided installation capability.
  • Fully annealed sleeve yields high sealing performance.
  • Improved seal and wider hole tolerance.
  • Larger hole tolerance. Simplified hole alignment when automated placing is required.
  • Internal lock. Flat nose tip and ease of use.
  • Improved stem retention and increased vibration resistance.
  • No locking ring formed by nose tip. Standard equipment reduces preventative maintenance.
  • Tapered sleeve and stem allows ease of entry with standard tooling.
  • Suited to automated systems, seal quality is not operator dependent
  • Available as a customized design to meet your unique assembly requirements.
  • Popular assembly applications include thin wall applications, restricted space, shorter hole length, high-pressure applications, holes with large tolerance, and automotive low-pressure applications.
